I have two max weight Cryztal GT's and they fly much more overstable for me then my ESP Buzzz.

They fly like a HSS 0 LSS 2 instead of a HSS -.5 LSS 1. The flight is very straight with a hard fade at the end of the flight. I put it right near a Wasp in stability. The plastic is amazing and feels great. I am really itching to throw them this summer and getting more work when it isn't freezing and I can actually get grip on the tee pads.

Now if I just had a 10 year buzzz so I could compare these two. I would bet this buzz GT is still a tad more overstable than the 10 year.

I was just commenting in the 10 yr. thread how these GT's fly nothing like the 10 yr discs. The GT's are much longer, I actually managed to throw them farther then my Stalker. I like them because they handle OAT very well, and if I mess up and over-torque them they come back every time.

The 10 yr. Buzzz's fly straight as an arrow, with very little HSS turn 0 or -0.25 and a 1.25 turn at the end.

I bought a couple, I have to say they feel really nice in your hand. My hope is once its beat in it will fly like a new Z Buzzz in terms of stability. If it stays too OS I'll just start carrying my X Buzzz along with it.
